In brief: Usually < 1yr
Pubertal gynecomastia may effect the majority of males as the begin their pubertal transition.
Most are minimal and last 6m to a year, but occasional longer episodes do occur (1-3yr) it is important to separate the true process from fatty breast enlargement that produces a false gynecomastia in overweight kids. Spongy glandular tissue directly under the nipple is absent in the false case.

In brief: 1-2 years
Difficult to pinpoint an “average” duration of adolescent gynecomastia; for many young men this process continues for 1 to 2 years before resolving spontaneously.
For many however the process continues into adulthood. Gynecomastia can be seen in all age groups.
